Two bridge type transducers are coupled in series with their outputs each driving one of a pair of differential amplifiers, with the outputs tied together in a push-pull configuration. In further embodiments, push-pull operation is obtained by matching amplifier gain components and using current mirrors. Lower voltage operation may be achieved by simple diode level shifting of the transducer outputs. In one embodiment, the transducers comprise Hall effect sensors.
